This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

This study investigated the types and distribution of rodents,and the infection status of eight pathogens in the high-altitude areas of western Sichuan,to provide a basis for control of rodent-borne diseases and pathogen surveillance in rodents in the area.From August to November of 2023,rodents were captured through the night method in high-altitude areas of western Sichuan.Nucleic acids were collected from the rodents'livers and lungs,and eight important pathogens were detected:Dabie bandavirus,Han-tavirus,Bartonella,Francisella tularensis,Anaplasma phagocytophilum,Rickettsia mooseri,Orientia tsutsugamushi,and Leptospira interrogans.The chi-square test was used to compare the composition ratios of rodent species and the difference in pathogen positivity rates among groups.A total of 114 rodents of nine species were captured.The dominant species in this area were Apodemus agrarius(22.81%),Apodemus chevrieri(18.42%),Niviventer confucianus(17.54%),Apodemus latronum(16.67%),and Apodemus peninsu-lae(13.16%).Other rodent species included Rattus nitidus(4.39%),Neodon irene(4.39%),Chodsigoa hypsibia(1.75%),and Nivi-venter excelsior(0.88%).Statistically significant differences in rodent species composition were observed among regions,altitudes,and habitats(χ2Region=112.358,P<0.05;χ2Altitude=96.843,P<0.05;χ2Habitat=48.842,P<0.05).The liver and lung pathogen results showed that the positivity rate of Bartonella was highest(29/114),whereas those of the other seven pathogens were 0%-4.39%.Five rodents were co-infected with two or more pathogens,and the composite positivity rate was 4.36%(5/114).Statistically significant differences in the positivity rates were observed for Leptospira interrogans among species(χ2=6.568,P=0.028)and Anaplasma phagocytophilum among habitats(χ2=7.596,P=0.027);however,no significant differences in the positivity rates of other pathogens were found among rodent species,regions,altitudes,habitats,and sexes(P>0.05).Thus,rodent species were abundant in the high-altitude areas of western Sichuan and carried a variety of pathogens.Multiple pathogens showed compound infections,among which the positivity rate of Bartonella was relatively high.The total infection rate of pathogens in living areas was relatively high,and the risk of pathogenesis to the population is greater.Therefore,rodent control and disease monitoring efforts should be strengthened.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Objective:To explore the correlation between factors such as life events and the incidence of alopecia areata.Methods:A retrospective study was carried out to incorporate 550 patients diagnosed with alopecia areata and 550 healthy controls in the Department of Dermatology and Aesthetic Medicine, Honghui Hospital, Xi＇an Jiaotong University from December 2012 to February 2022. Based on the circumstances 6 months prior to the disease onset, patients independently completed the questionnaire survey, encompassing the Life Events Scale (LES) and the General Questionnaire on Alopecia Areata. Univariate analysis was implemented on the general conditions of both the alopecia areata patients and the healthy controls. Factors with statistically significant disparities were incorporated into the multivariate unconditional logistic regression model to analyze the influencing factors of the occurrence of alopecia areata.Results:In the alopecia areata group, there were 256 males and 294 females, with an average age of (32.6±13.1) years. In the healthy control group, there were 256 males and 294 females, with an average age of (34.5±13.3) years. Statistically significant differences were identified in occupational nature, family history, character, personality, alcohol consumption, consumption of spicy and irritating foods, negative life events, family life issues, and learning and work problems between the alopecia areata group and the healthy control group (all P<0.05). The outcomes of the multivariate unconditional logistic regression model indicated that occupational nature ( OR=2.268, 95% CI: 1.212-4.242, P=0.010), family history ( OR=9.692, 95% CI: 1.177-79.773, P=0.035), personality ( OR=1.807, 95% CI: 1.020-3.203, P=0.043), and learning and work problems ( OR=1.095, 95% CI: 1.010-1.188, P=0.029) were the influencing factors of the incidence of alopecia areata. Conclusions:Occupational nature, family history, personality, and problems in learning and work are the influencing factors of the incidence of alopecia areata.

Objective:To explore the clinical value of multidisciplinary team (MDT) treatment model for retroperitoneal soft tissue sarcoma (RPS) in the context of a regional medical center.Methods:The diagnosis and treatment of a patient with RPS in MDT model who were admitted to Xiamen Branch, Zhongshan Hospital, Fudan University in October 2020 were summarized, and the literature was reviewed.Results:The patient was a 59-year-old male, he was diagnosed with retroperitoneal INI-1-deficient poorly differentiated sarcoma with multiple systemic metastases. After several rounds of MDT discussions in Shanghai headquarter and Xiamen Branch of Zhongshan Hospital, Fudan University, the patient received systemic antitumor therapy combined with local therapy. After active treatment, the patient obtained a good curative effect. During the follow-up period, the liver and lung lesions slowly enlarged, and the treatment plan was adjusted. The patient had survived for more than 3 years.Conclusions:The diagnosis and treatment of RPS is complex, and the MDT model in the context of a regional medical center can help to formulate the optimal treatment plan for patients and may maximize the survival benefit of patients.
